Objectives: The main objectives of this project is to test your ability to create and use C++ classes, with multiple constructors, static members/functions, and expand to operator overloading A review of pointers, structs, arrays, iostream, file I/O and C-style strings is also included. Description: This project will significantly expand upon Project 3 by adding additional functionality, and implementing more abstract data types (ADTs) and their operations through classes. Pointers must be used for all array manipulation, including arrays with ADTs (structs, classes) e.g, rental cars, rental agencies. Pointers must be used in function prototypes and function parameter lists - not square brackets. Make sure all your C-string functions (e.g. string copy, string compare, etc.) work with pointers (parameters list and function implementation). Const should be used in parameter lists, functions, and function signatures as appropriate. Sauare brackets should be used only when d Pointer arithmetic (e.g., ++ , +-, --,--) and setting the pointer back to the base address using the array name can be used to move through arrays. work with pointers paraneters lil hur p s and function parameter lists an array.or if otherwise you specify your own overloaded operator [1 The additional functionality is as follows: You are given an updated data file where there is 1 Agency location (Agency) which has 5 cars (Car) which can potentially be of a high-tech type. Each car can incorporate up to 3 (0-3) special driving sensors (Sensor). You will have similar menu options, but the functionality has been updated below. Note: using multiple helper functions to do smaller tasks will make this project significantly easier.
